Product Description
TRIPLETT 3072 BROWNIE METER W/CASE 8455L1 W/O BATTERY NEWThe Simpson 8455 Line Loop Testers (hereafter referred to as the 8455 or theInstrument) were specifically designed to analyze telephone line faults. Compact,rugged, and easy-to-use, they are capable of measuring DC voltage to 100volts and loop resistances to 2M (8455 V3) or 10K (8455A). The voltmeterfunction can be used to detect and measure any DC voltage on the line and theresistance ranges can be used to identify and locate line faults.The meter is of pivot-and-jewel construction with a 2-3/8″ diameter dial with knifeedgepointer that moves across a 2-3/16″ (100°) scale arc. Scales are as follows:POINTS: 0-100 for ballistic testsM-K: (8455 V3) 0-2M or 0-200k ranges; 0-10K (8455A)VOLTAGE: 0-100 POINTS = 0-100VDue to the 0-100° scale arc and the 0-100 dial calibrations, the accuracies of±2% of full scale and ±2° of scale arc are both represented by ±1 scale division ofthe POINTS scale anywhere on the scale.The 8455A differs from the 8455 V3 in that it substitutes a 0-10K range for the 0-200K range of the 8455 V3. The 2M range remains for points measurements,but does not have a separate meter dial scale.The 8455 V3 differs from earlier 8455 in that it incorporates a field replaceableswitch design. The 8455A shares the field replaceable switch design.Throughout this manual, “8455” will now refer to both the 8455 V3 and the 8455A,unless otherwise noted.Items and Accessories Furnished With This InstrumentQuantity Description Number1 Test Lead Set 450011 Battery, 45V, NEDA, Type 201 6-1133131 Operator’s Manual 6-1154581 Carrying Case 00836Table 2-2.
